Title: Crank angle position detector for engine
Inventor: SHIMIZU HIROKAZU
IPC: F02P3/045
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To improve control accuracy at the time of idling operation, and improve exhaust property by finding out a real measured angle by a measured result of a generation cycle in a zone where a time is measured, and a control time, and learning a value for correcting a control time on the basis of the real measured angle and a control angle. SOLUTION: When a position signal is outputted from a crank angle sensor 12 at the time of operation of an internal combustion engine 1, a generation cycle of a position signal is measured. It is judged whether this position signal is a signal corresponding to a referential signal or not. When 'YES' is judged, an angle measured by angle control and an angle measured by remaining time control are calculated. When a position signal after the referential signal is outputted, and when a position is not a control referential position for starting time control, a current-carrying cutoff timing and a current-carrying start timing are detected by time control. When the position signal just after detection is outputted, a correcting value for correcting a control time is learnt.

IPC: F01N1/08
Filed: 1985-06-26
Abstract: PURPOSE:To suppress uncomfortable feeling by dividing a muffler chamber into two parts by a partitioning wall and installing a communication pipe onto the partitioning wall and setting the opened port part of the exhaust pipe led from each air pipe oppositely to the opened port part of the communication pipe, thus reducing the sound pressure level of exhaust noise and securing the proper frequency component. CONSTITUTION:The air in a muffler shell 5 is divided into two muffler chambers 6 and 7 by a partitioning wall 10, and a communication pipe 11 is installed onto the partitioning wall 10. The downstream-side opened-ports of the exhaust pipes 1 and 2 of each cylinder of the engine equipped with even number of cylinders are arranged oppositely, keeping the communication pipe 11 interposed. Further, the opened ports at the upstream-side edge parts of the muffler pipes 8 and 9 are arranged oppositely, keeping the partitioning wall 10 interposed. Therefore, the sound pressure level of the exhaust noise can be reduced, and the frequency distribution of the exhaust noise is made free from uncomfortable feeling.

Title: Low-noise amplifier circuit
Inventor: TAKAGI KOTARO
IPC: H03F1/56
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To simplify the circuit constitution by decreasing the number of pins when a low-noise amplifier (LAN) circuit is constituted in an LSI and to suppress the input/output loss of an RF signal due to the switching of the circuit by compensating impedance, which is set at weak input time, at intense input time. SOLUTION: The LNA 1 and SW1 and SW2 which electrically connect its input and output to each other are provided on the same IC chip, and input/ output matching circuits 2 and 3 and a compensating circuit for impedance are additionally provided to the IC chip. This constitution requires only three pins of the IC chip. At weak input time, constants of the output matching circuits 2 and 3 are set to match impedance and when the circuit is switched at intense input time, the mentioned matching is compensated by the compensating circuit 4 to suppress the input/output loss of the RF signal. This compensation is carried out by setting the constant of the compensating circuit 4 so that the impedance of the parallel circuit composed of the LNA 1, input/output matching circuits 2 and 3, etc., resonate in a received signal band.
